Colorize (syntax highlight) JSON output

[zdila]

Currently JSON is printed with single color. It would be nice to add syntax highlighting which would make it easier to read especially in the single-line mode.

[mcollina]

Do you know if there is a module that could do that on the terminal?

[zdila]

Quickly googled for example https://www.npmjs.com/package/json-colorizer

[mcollina]

I would prefer an example that does not depend on Chalk, but overall it's a good feature to have.

@mcollina Opened joeattardi/json-colorizer#24, let's see what their stance is.

[kibertoad]

@mcollina In case there is no timely response, how would you feel about a PR embedding the json-colorizer functionality inside pino-pretty? It is a fairly small amount of code.

[mcollina]

no prob

[kibertoad]

@mcollina Any recommendations on where in existing codebase to plug in JSON colourizing?

[mcollina]

Not really, I would put it in a separate file for the ease of testing.

[kibertoad]

@mcollina Oh yes, that I would, I was more curious about where to invoke it from within existing code.

[mcollina]

pino-pretty/lib/utils.js

Line 346 in e5e3f54

function prettifyObject ({

seems a good function to start with.

FYI I've forked the repo to use colorette, so we could potentially use my fork here: https://www.npmjs.com/package/@capaj/json-colorizer

[mcollina]

If we need to fork I prefer it to live in the pino org: anyway, good work!

Could you start integrating that here?

[capaj]

not sure if I have access there, but I can fork my fork there if I do.

[capaj]

no I don't have access there. If you invite me, I can fork and publish it on npm under @pino/json-colorizer
